Ingredients You’ll Need

This dip is a beautiful example of how just a few simple ingredients can combine to make something truly remarkable. Each item plays a crucial role: the olive oil helps caramelize the onions to golden perfection, the onions give that iconic sweet-savory base, and the sour cream and mayonnaise create the ultra-creamy texture you expect from a dip like this.

2 tablespoons olive oil: Essential for slowly caramelizing the onions without burning them.
1 ½ cups chopped onion: The heart of this dip, bringing deep sweetness and complexity when caramelized.
3/4 teaspoon kosher salt, divided: Enhances all flavors and helps in seasoning the onions and the dip base.
1 cup sour cream: Adds creaminess and a slight tang for balance.
1 cup mayonnaise: Works with the sour cream to create a rich, smooth texture.
1/2 teaspoon garlic powder: Gives a subtle hint of garlicky warmth without overpowering the onions.
1/4 teaspoon ground white pepper: Adds a gentle peppery note that lingers on the palate.

How to Make Homemade French Onion Dip From Scratch Recipe

Step 1: Gather All Ingredients

Before you start, collect everything you need so the process goes smoothly and you can focus on getting that perfect caramelization and blending all flavors together perfectly.

Step 2: Caramelize the Onions

Heat the olive oil in a large skillet over medium heat, then add the chopped onions and 1/4 teaspoon kosher salt. Stir occasionally and cook until the onions turn a rich golden brown and become sweet and tender, about 20 minutes. Patience here is key—slow cooking brings out the natural sugars and transforms the onions into the dip’s signature flavor. Once done, remove from heat and allow them to cool for 5 to 10 minutes before mixing with the rest of the ingredients.

Step 3: Prepare the Creamy Base

While the onions are cooling, combine the sour cream, mayonnaise, garlic powder, white pepper, and the remaining 1/2 teaspoon kosher salt in a mixing bowl. Stir until everything is smooth and well incorporated. This mixture is where the dip gets its luscious texture and subtle tang.

Step 4: Combine and Chill

Fold the cooled caramelized onions gently into the creamy base. Make sure the onions are evenly distributed for that perfect bite every time. For best results, chill the dip for at least an hour to allow flavors to meld beautifully.

How to Serve Homemade French Onion Dip From Scratch Recipe

Garnishes

Simple garnishes can enhance both the look and taste of your dip. Try sprinkling freshly chopped chives or parsley on top for a pop of color and fresh herbal note. A light dusting of smoked paprika can add a subtle smoky warmth that complements the caramelized onion flavor wonderfully.

Side Dishes

Serve this dip with crispy potato chips, fresh vegetable sticks like carrots and celery, or crusty bread slices for dipping. It also pairs exceptionally well with warm pretzels or pita chips, making it a versatile option for any gathering or snack time.

Creative Ways to Present

For a fun twist, bake the dip in a small ovenproof dish topped with a sprinkle of shredded cheese and broil it for a few minutes to create a bubbly, golden crust. Alternatively, use hollowed-out mini bell peppers or cherry tomatoes as dipping vessels for a delightful finger food version that’s sure to impress.

Make Ahead and Storage

Storing Leftovers

This Homemade French Onion Dip From Scratch Recipe keeps beautifully in an airtight container in the refrigerator for up to 3 days. The flavors continue to meld and deepen, making leftovers even tastier. Just give it a quick stir before serving again.

Freezing

While freezing French onion dip is possible, the texture may change slightly upon thawing due to the dairy content. If you decide to freeze it, store the dip in a freezer-safe container for up to one month and thaw overnight in the fridge.

Reheating

Since this dip is best served cold or at room temperature, reheating isn’t usually necessary. If you have frozen it and prefer a warm dip, gently heat it on low in a saucepan, stirring frequently to avoid separating the cream and mayo.

FAQs

Can I use yellow onions instead of white onions?

Absolutely! Yellow onions work just as well and even lend a slightly sweeter flavor when caramelized. The key is to cook them slowly until golden and soft.

Is this dip suitable for a make-ahead party appetizer?

Yes, it’s perfect for making ahead since chilling allows the flavors to deepen. Just keep it refrigerated until serving and give it a quick stir.

Can I substitute Greek yogurt for sour cream?

Yes, Greek yogurt is a great substitute for a lighter version of this dip. It will add a bit more tang and protein while maintaining the creamy texture.

How long does the dip last in the fridge?

You can expect the dip to last for about 3 days in the fridge. Be sure to store it in an airtight container to keep it fresh and flavorful.

Can I add fresh herbs to the dip?
